Book excerpt: Prominent economists reconsider the fundamentals of economic policy for a post-crisis world. In 2011, the International Monetary Fund invited prominent economists and economic policymakers to consider the brave new world of the post-crisis global economy. The result is a book that captures the state of macroeconomic thinking at a transformational moment. The crisis and the weak recovery that has followed raise fundamental questions concerning macroeconomics and economic policy. These top economists discuss future directions for monetary policy, fiscal policy, financial regulation, capital-account management, growth strategies, the international monetary system, and the economic models that should underpin thinking about critical policy choices.
